FitPow[ <List of Points> ]
Calculates the regression curve in the form a x^b.
Example:
FitPow[{(1, 1), (3, 2), (7, 4)}] creates the regression curve f(x) = 0.97 x^{0.71}.


CAS Syntax

FitPow[ <List of Points> ]
Calculates the regression curve in the form a x^b.
Example:
FitPow[{(1, 1), (3, 2), (7, 4)}] yields 0.97 x^{0.71}.
